Discuss Cleaning Mould From Travertine in the Australia area at TilersForums. The USA and UK Tiling Forum (Also now Aus, Canada, ROI, and more)
Tilled an en-suite shower room about 7yrs ago, there is no window only an extractor fan.
The tiles are filled and honed travertine. The stone was all sealed when laid. I dont think it has been sealed again at any time.
There is now black mould that seems to be in any small imperfections.
What would be the best course of action to get this cleaned up and sealed.
Many thanks

i suggest the wife who chose it gives it a good clean with a tooth brush .

ok i give up here you go small pits will all ways go black its there nature if its been sealed it should still be sealed .you can use many loitions and posthions .but a quick way would be to use fine sand and water mix up like grout now grout over the lot then wash off the sand will pull the black marks off the grout if its been sealed .now tell the client not to use hand soap as this will speed up bactiera grouth x4 then use shower shine when they have a shower this will hold back the grouth but trav in a shower will always be on going maitance
As ray , this will be ongoing maintenance
I would suggest degrease the whole area with a mild alkali specific stone cleaner- we have power clean or wexa if really grubby. Test this
Work over areas with a white pad and stiff scrubbing brush into the holes.
If the mould is still apparent , test and spay over a mildew remover ( we have mildew away )this will remove remaining spore and inhibit.use the brush to work into holes. Let the stone dry 4-6 day or until fully dry and then re- impregnate with your original product.
Maintain with a stone specific cleaner and get the client to use the mildew product when spore re-appears .
